I am in Michigan where it drops below zero degrees through winter. I have a few pond plants I’d like to bring inside and try to save for next year. It’s not that they’re expensive to repurchase but they are incredibly hard to find around here! I like to have 1/3 of my pond covered in plants and trying to locate them has proven to be a big pain. I currently have some water lettuce, water hyacinth, and rain lily plants that will not survive winter. Any helpful tips on how to keep them inside for a few months! Thanks!
